Obviously there are solutions like this, which are very simple to try out.

However i strongly believe these spheres should not be used with hyper or cardioid mics, as it leaves an empty resonant chamber behind the capsule.

Since the holes of backplates are not sealed i can not imagine what kind of havoc it would do to FR of the mic, let alone pattern response.

The version i am talking about.
This capsule is also used in the KM83, KM130 and KM183.
‚Honeycomb‘ reflectors are also used in Schoeps capsules.

Not realized yet, but I bought this:


thought about this:

I think that this would be the best price performance combination. The only thing I don't know, how much polarization voltage this capsule need.
Would be voltages from M50 schematics sufficient ?

If it's 57v as specified in schematic, it should work just great.

As i used ST51 for this experiment 40v was a bit low, some noise issues at distance.

So i used an extra DC-DC board i had from Behringer B2 to get 60V, and it works great with my capsule.

Now that i am actually looking at the schematic for the first time, as i was going for Fet version, i see that 600pf cap anode to ground. Hm...
